The planted areas of the site are already at final grade and the way they handled the water was a very positive example of what we can expect in the future. The berm that runs adjacent to Comox Road was about 0.75-1m above the current flooding levels. This bodes well for our design in future climatic conditions. The site now has more capacity to deal with substantial amounts of water and the upland area of the site is about a meter higher than it was when the site was paved.
Once the wall is removed (date to be determined), the part of the site that was underwater during the latest king tides will be tidally influenced. It will be a diurnally (twice daily) wetted brackish area known as a tidal marsh. Brackish environments have a salinity in between fresh water and ocean water. The plants that we transplanted in that area are salt-tolerant and thrive in these variable conditions. They are fast growing and dormant during the winter months. For these reasons, they should weather this inundation of water well. While there is always a small degree of mortality with new plantings, we do not expect higher than normal rates at this time.
The site is holding the water, which is slowly leaving through the south end. The south end has turbidity and erosion control measures in place, including silt fences, silt curtains, and a rock swale. We are monitoring the turbidity of the water in the river to make sure our site is not negatively impacting the water quality in the river. We are keeping a close eye on our erosion measures and continue to monitor turbidity levels. To maintain the effectiveness of our erosion control measures we plan on reinforcing them before the next king tides at the end of January (Jan. 21-26).
Earthworks Continue at Kus-kus-sum
While the Kus-kus-sum site is already beginning to come into its own, there is still much work to be done. Just over one third of the area was recontoured and planted last year in 2022. Project Watershed aims to recontour and replant the remainder of the site this summer and fall, if funding allows. The key works you will see on site this year include recontouring and regrading, habitat complexing, and native species planting.

Forage Fish Map
Project Watershed has been surveying beaches for the presence of forage fish and forage fish eggs. The location of the beaches we surveyed last season are shown below. You can hover over each location to see if eggs were found.
